#  API DOCUMENTATION

## General

### Automation key

The authentication of the automation is performed via a secure key available in the D4 UI interface. Make sure you keep that key secret. It gives access to the entire database! The API key is available in the ``Settings`` menu under ``My Profile``.

The authorization is performed by using the following header:

~~~~
Authorization: YOUR_API_KEY
~~~~
### Accept and Content-Type headers

When submitting data in a POST, PUT or DELETE operation you need to specify in what content-type you encoded the payload. This is done by setting the below Content-Type headers:

~~~~
Content-Type: application/json
~~~~

Example:

~~~~
curl --header "Authorization: YOUR_API_KEY" --header "Content-Type: application/json" https://D4_URL/
~~~~
